Ranga Alur Puli is a traditional Bengali snack made with a spicy potato filling wrapped in a rice flour dough and then deep-fried. The filling is made with boiled and mashed potatoes, flavored with spices like cumin, turmeric, and red chili powder. The dough is made by mixing rice flour with water and salt. The filled dough is then shaped into small dumplings and deep-fried until golden and crispy. Ranga Alur Puli is a popular street food in Bengal and is often served with a tangy tamarind chutney.
